実験手順

(R)-5-Chloro-3-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-6,8-dimethylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione (9.2 g, 27.1 mmol, 1 eq, compound 8E),2-fluoro-4-iodoaniline (12.9 g, 54.2 mmol, 2 eq), tris(dibenzylideneacetone)dipalladium(0) (1.99 g, 2.17 mmol, 0.08 eq), 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (1.25 g, 2.17 mmol, 0.08 eq) and sodium tert-butoxide (7.81 g, 81.4 mmol, 3 eq) were heated in degassed anhydrous 1,4-dioxane (80 mL) at 100° C. for 1 hour. Upon cooling, the solution was filtered and the solid washed with DCM. The filtrate was evaporated in vacuo and the residue (crude 8F) was taken up in H2O (20 mL) and THF (20 mL). 1N HCl (15 mL) was added and the solution heated at 70° C. for 30 minutes. Upon cooling an off-white solid precipitated which was collected by filtration, washed with water and dried. The solid was purified by HPLC to give 4.2 g of title compound (31%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.63 (s, 3 H) 3.38 (t, J=6.06 Hz, 1 H) 3.41-3.51 (m, 1 H) 3.61 (s, 3 H) 3.62-3.68 (m, 1 H) 3.75 (br. s., 1 H) 4.81 (t, J=5.56 Hz, 1 H) 5.11 (d, J=5.31 Hz, 1 H) 6.60 (t, J=8.72 Hz, 1 H) 7.45 (d, J=9.60 Hz, 1 H) 7.66 (d, J=10.61 Hz, 1 H) 8.48 (s, 1 H) 10.16 (s, 1 H).
